Traditional topographic mapping is still hugely useful in many niches. Try laying a 100 mile pipeline, or building a factory, or organising search and rescue without traditional topo mapping. I would agree that it can be obtusely formatted and wildly expensive.

High resolution 3D modelling is already available in much of Norther Europe. It is very cool, but surprisingly difficult to actually make useful. In most applications comic book style generalisations actually work better.
